My TextView.setText() isn't working.

public class MainActivity extends ActionBarActivity {
WorldGen earth = new WorldGen("Earth", 5973, 9.78);//Create a World Object
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    if (savedInstanceState == null) {
        getSupportFragmentManager().beginTransaction()
                .add(R.id.container, new PlaceholderFragment())
                .commit();
    }
    setStartUpWorldValues();
    setStartUpScreenText();//ADDED
}    
protected void setStartUpWorldValues(){ 

earth.setPlanetColonies(1);         // Set Planet Colonies to One
earth.setPlanetMilitary(1);         // Set Planet Military Bases to One
earth.setColonyImmigration(1000);       // Set Planet Population to 1000
earth.setBaseProtection(100);           // Set Planet Armed Forces to 100
earth.turnForceFieldOn();           //  Turn On the Planet Force Field
}
public void setStartUpScreenText(){
    TextView planetNameValue = (TextView)findViewById(R.id.dataView1);
    planetNameValue.setText(earth.planetName);
    TextView planetMassValue = (TextView)findViewById(R.id.dataView2);
    planetMassValue.setText(earth.planetMass);
    TextView planetGravityValue = (TextView)findViewById(R.id.dataView3);
    planetGravityValue.setText(String.valueOf(earth.planetGravity));
    TextView planetColoniesValue = (TextView)findViewById(R.id.dataView4);
    planetColoniesValue.setText(earth.planetColonies);
    TextView planetPopulationValue = (TextView)findViewById(R.id.dataView5);
    planetPopulationValue.setText(String.valueOf(earth.planetPopulation));
    TextView planetMilitaryValue = (TextView)findViewById(R.id.dataView6);
    planetMilitaryValue.setText(earth.planetMilitary);
    TextView planetBasesValue = (TextView)findViewById(R.id.dataView7);
    planetBasesValue.setText(earth.planetBases);
    TextView planetForceFieldValue = (TextView)findViewById(R.id.dataView8);
    planetForceFieldValue.setText(String.valueOf(earth.planetProtection));
    //setContentView(R.layout.activity_main); DELETED

} //etc

/So my setText() method doesn't change the default value that I have in the XML file. Should I put the content of setStartUpScreenText() method in the onCreate method? Can it work outside of it?/

Now the application close after running.

Remove your setContentView() function call at the end of your function setStartUpScreenText(). You are doing setContentView after initializing all values. You must do setText after

setContentView(R.layout.activity_main);

First call setContentView() with the xml you want to load. Then, call the initialization functions on the controls present on that view xml.

A parameter to some of the setText() calls is an int. Therefore the setText(int) overload that attempts to set the text with a resource id is used instead of setText(CharSequence) that uses a string.

To explicitly use setText(CharSequence), use e.g. setText(Integer.toString(earth.someintegervalue)).

Remove setContentView(...) from setStartUpScreenText(). It looks like you are setting the text and then setting the screen back to its original state.

You can check also if your Textview linked to any TextWatcher or Filter then trace it.
